I don't know anything about that coolwallet and I hope this post is not about advertising that particular hardware wallet.
Anyway, ledger is one of the most popular. Other wallets such as trezor and coldcard have been proven good as well. Just make sure you buy from their official websites to avoid getting tampered wallets.

Ah well, the "other newbie" came in quick to answer his/her own question lol.
That is not the best way to shill your wallet
